Thist patch removes the depends on USB_EHCI_HCD that the various USB EHCI HCD drivers use and encloses every driver within an if USB_EHCI_HCD / endif block. The EHCI HCD platform and Octeon drivers have been moved around to remain enclosed within this block.

Just like the OHCI counter part we just can remove the architecture specific symbols which prevent these configuration symbols from being selected by platforms/architectures requiring it. The original implementation did not scale at all since it required each and every single architecture to be added for these configuration symbols to be selected. Now it is up to the EHCI driver and/or platform to select these configuration symbols accordingly.

This patch removes the depends on USB from all config symbols in drivers/usb/host/Kconfig and replace that with an if USB / endif block as suggested by Alan Stern. Some source ... Kconfig lines have been shuffled around to permit a better regroupment of the Kconfig files depending on "config USB" item. No functionnal change is introduced.

7edb3daf: (USB: EHCI: make ehci-s5p a separate driver) raised an issue with ehci-s5p's driver data. Now that 's5p_ehci_hcd' doesn't maintain pointer to 'usb_hcd' and s5p_ehci is nothing but a pointer to hcd->priv; add hcd to the driver data rather than s5p_ehci. This fixes issues with null pointer dereferencing in s5p_ehci_shutdown(), s5p_ehci_suspend(), s5p_ehci_resume().

Separate the Orion host controller driver from ehci-hcd host code into its own driver module because of following reason. With the multiplatform changes in arm-soc tree, it becomes possible to enable the mvebu platform (which uses ehci-orion) at the same time as other platforms that require a conflicting EHCI bus glue. At the moment, this results in a warning like drivers/usb/host/ehci-hcd.c:1297:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1277:0: note: this is the location of the previous definition drivers/usb/host/ehci-orion.c:334:31: warning: 'ehci_orion_driver' defined but not used [-Wunused-variable] and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e023203 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the orion bus glue. An earlier version of this patch was included in 3.9 but caused a regression there, which has subsequently been fixed. While we are here, use the opportunity to disabiguate the two Marvell EHCI controller implementations in Kconfig. In V4 (arnd): - Improve Kconfig text In V3: - More detail provided in commit message regarding this patch. - Replaced hcd_name string "ehci-orion" into "orion-ehci". - MODULE_LICENSE is GPL v2. - In ehci_init_driver calling second argument passed as NULL instead of ehci_orion_overrides because ehci_orion_overrides is removed.

There are no functional changes in this patch. However, because the compliance mode timer can be deleted in more than one function, it seemed expedient to include the function name in the debug strings. Also limited the use of capitals to the first word in the compliance mode debug messages, except after a function name where all words start with lower case, in keeping with the style prevalent elsewhere in xhci.c.

The udc uses an shared dma memory space between hard and software. This memory layout is described in ci13xxx_qh and ci13xxx_td which are marked with the attribute ((packed)). The compiler currently does not know about the alignment of the memory layout, and will create strb and ldrb operations. The Datasheet of the synopsys core describes, that some operations on the mapped memory need to be atomic double word operations. I.e. the next pointer addressing in the qhead, as otherwise the hardware will read wrong data and totally stuck. This is also possible while working with the current active td queue, and preparing the td->ptr.next in software while the hardware is still working with the current active td which is supposed to be changed: writeb(0xde, &td->ptr.next + 0x0); /* strb */ writeb(0xad, &td->ptr.next + 0x1); /* strb */ <----- hardware reads value of td->ptr.next and get stuck! writeb(0xbe, &td->ptr.next + 0x2); /* strb */ writeb(0xef, &td->ptr.next + 0x3); /* strb */ This appeares on armv5 machines where the hardware does not support unaligned 32bit operations. This patch adds the attribute ((aligned(4))) to the structures to tell the compiler to use 32bit operations. It also adds an wmb() for the prepared TD data before it gets enqueued into the qhead.

However it can also happen that the cleanup path is run before the transceiver was initialized (or the operating mode isn't set to TEGRA_USB_OTG) and is therefore NULL.

Commit 756aa6b3 (ehci-hub: improved over-current recovery) added port power cycling on overcurrent indications as needed by the MPC8349 USB controller after resolving of the overcurrent situation in order to have the host state machine assert the correct port status again. Commit 81463c1d (EHCI: only power off port if over-current is active) solved a thus resulting issue of endless overcurrent changes in combination with the MAX4967 USB power supply chip that signals overcurrent when power is not enabled by only powering off a port if the overcurrent is currently active. Added quirks flag need_oc_pp_cycle in order to specify the needed behaviour as there is no common behaviour that can comply with both requirements.

But some of the modules will eventually consist of more than one object file, e.g. for mass storage there will be f_mass_storage.o and storage_common.o. The resulting module cannot be called f_mass_storage.ko due to cyclic dependency. This patch introduces a naming scheme for the said resulting modules: usb_f_xxxxxx.ko e.g. usb_f_mass_storage.ko, usb_f_ss_lb.ko, usb_f_rndis.ko etc. Signed-off-by: NAndrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

Write "udc-name" will bind the gadget. Write an empty string (it should contain \n since 0 bytes write get optimzed away) will unbind the UDC from the gadget. The name of available UDCs can be obtained from /sys/class/udc/ v4…v5 - string rework. This will add a strings folder incl. language code like strings/409/manufacturer as suggested by Alan. - rebased ontop reworked functions.c which has usb_function_instance which is used prior after "mkdir acm.instance" and can be directly used for configuration via configfs. v3…v4 - moved functions from the root folde down to the gadget as suggested by Michał - configs have now their own configs folder as suggested by Michał. The folder is still name.bConfigurationValue where name becomes the sConfiguration. Is this usefull should we just stilc configs/bConfigurationValue/ ? - added configfs support to the ACM function. The port_num attribute is exported by f_acm. An argument has been added to the USB alloc function to distinguish between "old" (use facm_configure() to configure and configfs interface (expose a config_node). The port_num is currently a dumb counter. It will require some function re-work to make it work. scheduled for v5: - sym linking function into config. v2…v3 - replaced one ifndef by ifdef as suggested by Micahał - strstr()/strchr() function_make as suggested by Micahł - replace [iSerialNumber|iProduct|iManufacturer] with [sSerialNumber|sProduct|sManufacturer] as suggested by Alan - added creation of config descriptors v1…v2 - moved gadgets from configfs' root directory into /udcs/ within our "usb_gadget" folder. Requested by Andrzej & Michał - use a dot as a delimiter between function's name and its instance's name as suggested by Michał - renamed all config_item_type, configfs_group_operations, make_group, drop_item as suggested by suggested by Andrzej to remain consisten within this file and within other configfs users - Since configfs.c and functions.c are now part of the udc-core module, the module itself is now called udc. Also added a tiny ifdef around init code becuase udc-core is subsys init and this is too early for configfs in the built-in case. In the module case, we can only have one init function.

It possible to allocate the tty port number within the "instance" structure of the function and there is no need to expose this information within the gadget and therefore it is removed here. This patch converts only f_acm and all its users. The other gadgets will follow once the function is converted to the function interface.

the u_ether.c file has a global variable named the_dev which keeps a pointer to the network device after it has been created via gether_setup_name(). It is only used internally by u_ether. This patches moves the variable to its users and passes it via the port.ioport where it is saved later anyway.
